T. STEWART BROWN, OF PHILADELPHIA,

PENNSYLVANIA.

Specification forming part of Letters Patent No. 54,8119, dated May 22,1866.

To all whom it may concern: Y

Be it known that I, T. STEWART BROWN, of Philadelphia, Pennsylvania,have invented an Improved Trunk-Lock; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

My invention consists ot' a trunk-lock constructed in the peculiarmanner fully described hereinafter, so as to afford a more securefastening than trunk-locks of the ordinary construction.

In order to enable others skilled in the art to make and usemyinvention, I will now proceed to describe its construction andoperation. On reference to the accompanying drawings, which form part ofthis specification, Figures l and 2 are rear views, partly in section,of the hinged portion of the lock 5 Fig. 3, a rear view of part of thehinged portion and socket-p1ate, and Fig. 4 a vertical section on theline I 2, Fig. 3.

Similarletters refer to similar parts throughout the several views.-

The lock consists of two parts, which I have termed the hinged portion 7andthe socket.7 The hinged portion consists of a plate, A, secured tothe lid E of a trunk, and hinged to a plate, B, which carries the lock,the latter being an oblong case, a, secured to or forming a part of theplate B, and containing, in the present instance, two bolts, b and b',one projecting through one edge and the other through the opposite edgeof the said case a. The two bolts are connected together so as tooperate in unison by a lever, d, hung to a pin, e, one arm of the leverprojecting into a notch in the bolt b and the other arm into a notch inthe bolt b. A single key, D, is used to operate the upper bolt, b, thekey being made as usual with any desired number of Wards, and the lockbeing furnished with any appropriate system of tumblers.

Into the front F of the trunk is let a socket, G, consisting of a plate,f, and a casing, h, which forms a chamber adapted for the reception ofthe lock-case a, the case h of the socket having a suitable opening oneach vertical edge for the reception of the bolts.

In the locks generally used on trunks the lock itself` is secured to thebody of the trunk, While a plate containing a staple for the receptionof the bolt is hinged to the lid. The se curity of the lock, therefore,depends on this staple, which frequently breaks.

It will be seen that in my lock the entire duty performed by the boltsis to maintain the loclccase a within the chamber of the socket, andthat the tendency of the lid to be forced upward from the body of thetrunk is resisted by the entire case o and the socket; hence my improvedlock affords a much more secure fastening for trunks than ordinarylocks.

I claim as my invention and desire to secure by Letters Patent- Thecombination of the two bolts l) and b', arranged in respect to the casea and operatin g substantially as and for the purpose herein set forth.y

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

T. STEWART BROWN.
